The Chinese government's top diplomat Wang Yi has walked out before the start of a gala dinner of foreign ministers at a meeting in Cambodia and was seen leaving the venue in a vehicle, witnesses say.
Wang Yi waved to media as he entered a holding room for the dinner then walked out of the venue, without giving a reason, according to Reuters journalists.
Two witnesses working at the venue told Reuters Wang Yi was seen leaving in a vehicle.
The dinner was attended by more than a dozen foreign ministers including US Secretary of State Antony Blinken, Japan's Yoshimasa Hayashi, and senior diplomats of the Association of Southeast Asian Nations (ASEAN).
